Book Synopsis Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana by : Laurie J. Bryant
Download or read book Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana written by Laurie J. Bryant and published by Univ of California Press. This book was released on 1989-01-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.

Book Synopsis The Principal Diseases of Lower Vertebrates by : H. Reichenbach-Klinke
Download or read book The Principal Diseases of Lower Vertebrates written by H. Reichenbach-Klinke and published by Elsevier. This book was released on 2013-10-22 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Principal Diseases of Lower Vertebrates presents the material published by Heinz H. Reichenbach-Klinke between 1957 and 1962 in three separate volumes as ""Krankheiten der Aquarienfische"" (Alfred Kernen, Stuttgart), ""Krankheiten der Amphibien,"" and ""Krankheiten der Reptilien"" (Gustav Fischer, Stuttgart). The scope of the work has been enlarged with material contributed by E. Elkan who has also done the translation. Representatives of the main groups of parasites affecting fish have been presented as far as possible. The book is organized into three parts covering the diseases of fishes, amphibians, and reptiles. Experience has shown that those who keep, or are interested in, one kind of lower vertebrate will sooner or later also take an interest in one of the other groups. It was therefore thought expedient to include what is at present known of lower vertebrate pathology in one volume, even at the risk of some repetition where fishes, amphibians, and reptiles suffer from similar diseases or are the victims of identical parasites.

Book Synopsis Viruses of Lower Vertebrates by : Winfried Ahne
Download or read book Viruses of Lower Vertebrates written by Winfried Ahne and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention to viral infections and pathology previously focussed on diseases of economically important fish. In recent years, however, much new information on molecular virology and oncogenicity derives from viruses occurring in amphibians. New insights into the field of zoonosis were gained by studies of lower vertebrates serving as intermediate hosts in multiple human infections. Certain viruses, e.g. the influenza virus or calicivirus, seem capable of bridging species lines and even the land - sea interface. Global developments in aquaculture are indicated in influenza pandemics. These proceedings present research findings on viruses of fish, amphibians and reptiles, including defence mechanisms, zoonoses, evolutionary considerations and diagnostic approaches.

Download or read book The Riverside Natural History, Vol. 3 written by John Sterling Kingsley and published by Forgotten Books. This book was released on 2015-06-26 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Riverside Natural History, Vol. 3: Lower Vertebrates A very direct and personal interest attaches to the study of the Vertebrata, that branch of the animal kingdom to which man himself belongs, and of which he is in many respects the highest member. Many of the most interesting problems connected with man's place in nature can only be intelligently approached if the student is possessed of a certain degree of acquaintance with the structure of the animals built upon the same fundamental plan as himself. There can therefore be no more fitting introduction to the special description of structure and habits of the various groups of vertebrates than an attempt to indicate the anatomical features which are common to all, and the chief lines of modification of them. The object of the following pages will thus be to afford the reader some general stand-points, from which he may view the details embodied in the description of the separate groups, and at the same time to indicate the directions in which anatomists are at present working. Since the appearance of Darwin's origin of species, a quarter of a century ago, a flood of light has been shed on comparative anatomy, by the labors of those anxious to test the applicability of the doctrine of evolution within the domain of their special researches. However far we may still be from the solution of the question how and why the series of animal forms at present on the earth's surface differ from those of past geological periods, the general consensus of opinion is that they have descended from them. It is impossible, within the scope of the present work, to present in a connected form the evidence on which this opinion is based; but the description of structure and development, as well as of the fossil forms, having been prepared in the light of the evolution theory, will render it an easy matter for the reader to discover their hearings upon that doctrine. Thanks to the immense quantities of fossil vertebrates obtained from this country, the paleontological evidence for the theory of evolution is more complete of information in this branch than in any other; and thus the systematist, having regard to these different sources, is enabled, by the construction of genealogical trees, to indicate near or remote kinship, and to illustrate, as far as can be done from our imperfect knowledge, the phylogeny or line of development of the various groups. Since Lamarck, in the beginning of this century, first drew a sharp distinction between animals with and without backbones, the use of the terms vertebrate and invertebrate has become almost a part of popular language. Just as, however, the zoologist is obliged to restrict his use of the term fish to a narrower than the popular sense, so the advance of knowledge has led him to recognize affinities which oblige him to extend the term Vertebrata further than its etymology would justify. The conception embodied in that term is of animals possessed of a backbone formed of joints - the 'vertebrae' - having a certain amount of motion on each other.

Book Synopsis Nondestructive Biomarkers in Vertebrates by : Cristina Fossi
Download or read book Nondestructive Biomarkers in Vertebrates written by Cristina Fossi and published by CRC Press. This book was released on 2020-01-29 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive Biomarkers in Vertebrates presents an innovative approach for hazard assessment in vertebrates based on nondestructive rather than destructive methods. The book reviews the state of the art and defines the development and validation procedure of this new strategy. Biological materials, such as blood samples, epithelial tissue, eggs, feathers, and feces that can be obtained without stress or damage to the animal are suggested. Certain traditional studies (blood esterases, blood chemistry, mixed function oxidases, porphyrins, DNA damage, and cytological changes) can be performed on these specimens, along with new tests requiring only very small samples. This approach is developed to benefit protected, threatened species whose existence cannot be further jeopardized by the use of destructive methods. This volume will be particularly useful to ecotoxicologists, wildlife protection personnel, environmental consultants, and conservationist organizations.

Book Synopsis Autonomic Nerve Function in the Vertebrates by : S. Nilsson
Download or read book Autonomic Nerve Function in the Vertebrates written by S. Nilsson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intention of this book is to offer a comprehensive description and discussion of autonomic nerve function in the vertebrates from several points of view. Sections on anatomy, biochemistry of the transmitter substances and the structure, physiology and pharmacology of the different types of autonomic neurons have been included, together with chapters dealing with the autonomic nervous control of some organs and organ systems in the different vertebrate groups. Although knowledge in several of these areas is based primarily on studies of mammals, a certain emphasis has been placed on the autonomic nerve functions in the non-mammalian vertebrates to describe, from a comparative physiological point of view, the adaptations and possible "phylogenetic trends" in the development of the autonomic nerve functions in the vertebrates. It is very obvious that the literature created by the vigorous research activities within the fields of autonomic nervous anatomy, histochemistry, biochemistry, pharmacology and physiology is vast indeed, and not all aspects of the subject may have received fair treatment in the present volume. With an analogy from astronomy, it is hoped that the mass compressed into this book has reached the level of an energy-emitting neutron star, rather than the black hole which would be the result of compressing too large a mass.
Book Synopsis The Endocrinology of Growth, Development, and Metabolism in Vertebrates by : Martin Schreibman
Download or read book The Endocrinology of Growth, Development, and Metabolism in Vertebrates written by Martin Schreibman and published by Academic Press. This book was released on 2012-12-02 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Endocrinology of Growth, Development, and Metabolism in Vertebrates provides an overview of vertebrate endocrinology. This book aims to strengthen the bridge between medical and comparative endocrinologists by addressing the benefits that they can derive from this association. Organized into five parts encompassing 24 chapters, this volume starts with a discussion on the structure and biological function of growth hormone (GH) and prolactin (PRL) family. This book then explains the extrinsic, genetic, and humoral factors that influence animal growth, particularly in poikilotherms. This text also elaborates the environmental conditions that affect the growth of poikilotherms, including food availability, temperature, and photoperiod. Other chapters discuss how somatotropin affects the growth development in homeotherms, such as livestock species. The reader is also introduced to the metabolic actions of GH, which can be described in terms of short-lived insulin-like effects. Endocrinologists, molecular endocrinologists, biologists, molecular biologists, biochemists, researchers, and physicians will find this book extremely useful.
